Can the STUSB4500 support a USB C DRP and USB PD (sink-only) application using the SOM OTG interface illustrated above? Can it drive the VBUS, OC, and ID inputs and receive the EN output? We would like our product to serve as USB UFP (device), USB DFP with 5V VBUS (to support thumb drives), and to receive power from USB PD.

Hello

Can you please provide link of 'SOM OTG interface' you are mentioning ?

STUSB4500 is autonomous sink USB PD controller . Thus it can make valid PD contract with DRP (the DRP will connect as source) and Source only application. Sink to sink is not a valid connection: so it cannot connect to sink only application.

I do not understand clearly the question: if you can re phrase...

Thanks a lot !

Best regards
